View Patent ↗An electronic part ( 100 ) that shields parts on a substrate ( 101 ) includes a plurality of chip parts ( 102 ) each having on a respective end portion a ground terminal ( 103 A) and an electrode terminal ( 103 B) that supplies a voltage source, and located at regular intervals on the substrate with the respective ground terminals aligned, the ground terminal and the electrode terminal being electrically connected to a ground terminal land ( 107 A) and an electrode terminal land ( 107 B) of the substrate respectively; and a shielding case ( 104 ) that shields the plurality of chip parts and includes an opening ( 105 ) through which a resin is to be provided for securing strength of the respective electrical connection points of the ground terminal land and the electrode terminal land of the substrate with the ground terminal and the electrode terminal of the chip parts; the opening being formed such that an edge ( 106 ) of the opening becomes parallel to the ground terminal of the respective chip parts, and such that upon being warped the opening edge and the ground terminal of the respective chip parts contact each other, and such that upon being a portion of said chip parts other than a grounding part opposes the opening without contacting the edge of the opening.
1. An electronic part that includes parts shielded on a substrate, comprising:
a plurality of chip parts each having on a respective end portion a ground terminal and an electrode terminal that supplies a voltage source, and located at regular intervals on said substrate with the respective ground terminals aligned, said ground terminal and said electrode terminal being electrically connected to a ground terminal land and an electrode terminal land of said substrate respectively; and
a shielding case that shields said plurality of chip parts and includes an opening through which a resin is to be provided for securing strength of the respective electrical connection points of said ground terminal land and said electrode terminal land of said substrate with said ground terminal and said electrode terminal of said chip parts; said opening being formed such that an edge of said opening becomes parallel to said ground terminal of the respective chip parts, and such that upon being warped said opening edge and said ground terminal of the respective chip parts contact each other, and such that upon being a portion of said chip parts other than a grounding part opposes said opening without contacting said edge of said opening.
2. The electronic part according to claim 1 , wherein peripheral parts lower in height than said chip parts are located around the respective chip parts.
3. The electronic part according to claim 1 , wherein said opening is formed in a rectangular shape, and said chip parts is located such that said ground terminals are linearly aligned along said opening edge that constitutes one side of said rectangle.
4. The electronic part according to claim 3 , wherein plurality of chip parts is located such that said plurality of ground terminals is linearly aligned along said opening edge opposing said one side of said rectangle.
5. The electronic part according to claim 3 , wherein plurality of chip parts is located such that said plurality of ground terminals is linearly aligned along a side orthogonal to said opening edge constituting said one side of said rectangle.
6. The electronic part according to claim 3 , wherein said opening edge constituting said one side of said rectangle is formed in a stepped shape, and said plurality of chip parts is located such that said plurality of ground terminals is linearly aligned along a respective side of said stepped portion.
7. The electronic part according to claim 1 , wherein, in the case where said plurality of chip parts is separated in a plurality of groups on said substrate, said shielding case includes a plurality of openings, and said openings are formed such a respective edge thereof becomes parallel to said ground terminal of said plurality of chip parts of each group.
8. A method for arranging a shielding case and a plurality of chip parts, comprising:
locating at regular intervals on a substrate said plurality of chip parts each having on a respective end portion a ground terminal and an electrode terminal that supplies a voltage source, such that the respective ground terminals are aligned, and electrically connecting said ground terminal and said electrode terminal to a ground terminal land and an electrode terminal land of said substrate respectively;
forming an opening on said shielding case through which a resin is to be provided for securing strength of the respective electrical connection points of said ground terminal land and said electrode terminal land of said substrate with said ground terminal and said electrode terminal of said chip parts; and
forming said opening such that an edge of said opening becomes parallel to said ground terminal of the respective chip parts, and such that upon being warped said opening edge and said ground terminal of the respective chip parts contact each other, and such that upon being a portion of said chip parts other than a grounding part opposes said opening without contacting said edge of said opening.
